Betaineisetyenziswa njengento yokutsala ukutya kwezilwanyana zasemanzini.

Ngokutsho kwemithombo yangaphandle, ukongeza i-0.5% ukuya kwi-1.5% ye-betaine ekutyeni kweentlanzi kunefuthe elinamandla elivuselelayo kwiimvakalelo ezivumbayo kunye ne-gustatory yazo zonke ii-crustaceans ezifana neentlanzi kunye ne-shrimp. Inomtsalane wokutya okunamandla, iphucula ukuthandeka kokutya, inciphisa ixesha lokutya, ikhuthaza ukugaya kunye nokufunxa, ikhawuleza ukukhula kweentlanzi kunye ne-shrimp, kwaye igweme ukungcoliswa kwamanzi okubangelwa yinkunkuma yokutya.

Betaineyinto ekhuselayo yokuguquguquka koxinzelelo lweosmotic kwaye inokusebenza njengomkhuseli weseli osmotic. Inokuphucula ukunyamezela kweeseli zebhayoloji kwimbalela, ukufuma okuphezulu, ityuwa ephezulu, kunye neendawo eziphezulu ze-osmotic, zithintela ukulahleka kwamanzi kunye nokungena kwetyuwa, ukuphucula umsebenzi wepompo ye-Na K yeembrane zeseli, ukuzinzisa umsebenzi we-enzyme kunye nomsebenzi we-biological macromolecule, ukulawula i-tissue cell osmotic uxinzelelo kunye nokulinganisela kwe-ion, ukugcina i-nutrient absorption function, kunye nokuphucula i-osmotic organisms utshintsho olukhulu, ukunyamezela kwabo kuyanda kwaye izinga labo lokusinda liyenyuka.

 Betaineinokubonelela ngamaqela e-methyl kumzimba, kunye nokusebenza kwayo ekuboneleleni amaqela e-methyl ngamaxesha e-2.3 ye-choline chloride, okwenza kube ngumnikeli we-methyl osebenzayo. I-Betaine inokuphucula inkqubo ye-oxidation ye-fatty acids kwi-cell mitochondria, yandisa kakhulu umxholo we-long-chain acyl carnitine kunye nomlinganiselo we-long-chain acyl carnitine ukukhulula i-carnitine kwi-muscle kunye nesibindi, ukukhuthaza ukubola kwamafutha, ukunciphisa i-fat deposition kwisibindi kunye nomzimba, ukukhuthaza iprotheyini ye-protein, ukusabalalisa kwakhona i-carcass incidence, kunye nokunciphisa i-fatty yesibindi.
